[PATCH] ath6kl: Clear WPS ctrl flag if zero length IE is received from CFG

[Raja Mani]

Connect control flag CONNECT_WPS_FLAG has to be cleared
by default even if the driver receives zero length IE
from CFG.

Otherwise this flag would be always set after WPS exchange
which would lead wpa_supplicant to fail to connect with
the received WPS credentials. This issue is observed only
in OPEN security.

Thanks, applied. But I did a s/CFG/cfg80211/ in the commit log.
